Abstract:
Taking into consideration of optimization methods has been increased recently. Optimization methods in engineering that consumes a lot of time and cost have been developed. Optimal design of structures is a matter that grabbed the attention of civil engineers and due to the deficiency of classical methods the modern approaches are being developed. One of the most important structures that are constructed for industrial and transportation purposes are truss structures.Structural control under support excitation is constraining the structure to some structural limitations. The final target in this paper is to apply the modern methods to get the optimal weight of structure under seismic loads. Using a genetic algorithm-based optimization, the total optimal weight is predicted andthese are the inputs of the neural network that is to be trained. Optimizing the structure in these ways supports the structural design limitations to apply. Finally they are compared in a way to get the results.
